Historical Volatility Calculation

Calculation

Historical volatility calculation quantifies the degree of price variation of an asset over a specified past period. It is typically derived by computing the standard deviation of logarithmic returns of the asset’s price. This statistical measure provides an empirical basis for understanding past price fluctuations, which is crucial for risk assessment and derivative pricing. The calculation can be performed using daily, weekly, or monthly price data, depending on the desired time horizon. This provides a quantitative measure of past risk.
